<h2 class="atx" id="运算符重载就是让原本已经存在的运算符有了新的用法和意义">运算符重载就是让原本已经存在的运算符有了新的用法和意义</h2>
<h2 class="atx" id="运算符重载形式">运算符重载形式</h2>
<p><strong>[返回值] operator [运算符]（参数...） {...}；</strong></p>
<h3 class="atx" id="（一）参数">（一）.参数</h3>
<h4 class="atx" id="no1：">No.1：</h4>
<p>重载的运算符的参数个数必须与运算符原意的个数一致。比如+号的参数就是左加数和右加数两个。那么当我们重载加号时也要保证有左右两个加数作为参数。</p>
<h4 class="atx" id="no2：">No.2：</h4>
<p><strong>重载作为普通函数时：</strong></p>
<p>&nbsp;&nbsp;&nbsp;&nbsp;单目：右操作数是形参；双目：左边形参作为运算符左操作数 ，右边形参作为右操作数。</p>
<p><strong>重载作为类的成员函数时：</strong></p>
<p>&nbsp;&nbsp;&nbsp;&nbsp;如果运算符参数只有一个，那么不需要写参数；如果运算符参数有两个，那么只需要写一个参数。</p>
<p>&nbsp;&nbsp;&nbsp;&nbsp;因为类的成员函数默认有一个this指针。它会直接指向类本身。换句话说，当我们写出运算符重载时，有一个参数就已经被this指针包含了。</p>
<ul>
<li><p>单目运算符，this所指向运算符右参数，因为单目运算符的参数一般都在右边。</p>
</li>
<li><p>双目运算符，this指向运算符左参数。</p>
</li>
</ul>
<p>&nbsp;&nbsp;&nbsp;&nbsp;以减号为例，两个时间类a和b相减时。如果是a - b,那么this指针指向a，反之则指向b。在声明函数时，我们只需要写右参数即可。a - b的话只需要写 int operator-(Time b);</p>
<p>&nbsp;&nbsp;&nbsp;&nbsp;当然，单目运算符由于只有一个参数，且该参数被this所指向，那么我们无需声明任何参数即可。</p>
<h3 class="atx" id="（二）-返回值">（二） .返回值</h3>
<p><strong>运算符的返回值类型取决于该重载函数的作用是什么。</strong></p>
<p>&nbsp;&nbsp;&nbsp;&nbsp;比如a + b的作用是得到一个加数，那么返回值就是a+b的值。a += b的作用是让a的值改变，既然是让参数a的值改变，那么就无需返回值。</p>
<p>&nbsp;&nbsp;&nbsp;&nbsp;还有就是如果我们需要运算符支持多次操作那么也需要返回值。比如流插入运算符&lt;&lt;。我们可能需要多次进行插入，像cout &lt;&lt; a &lt;&lt; b &lt;&lt; c;之类就需要返回流ostream本身以便于之后的流插入工作。</p>

<h2 class="atx" id="重载限制">重载限制</h2>
<p><strong>1 ，</strong> 重载后的运算符必须至少有一个操作数是用户另一的类型，这将防止用户为标准类型重载运算符，因此，不能将减法运算符( - )重载为计算两个double类型的和，而不是他们的差。虽然这种限制将对创造型有影响，但是可以确保程序正常运行。</p>
<p><strong>2，</strong> 使用运算符重载是不能违反运算符原来的句法规则。例如不能将求模运算符（%）重载成使用一个操作数。</p>
<pre><code class="fenced-code-block language-cpp"><span class="token keyword">int</span> x<span class="token punctuation">;</span>
Time shiva<span class="token punctuation">;</span>
<span class="token operator">%</span>x <span class="token punctuation">;</span><span class="token comment">//错误</span>
<span class="token operator">%</span> shiva<span class="token punctuation">;</span> <span class="token comment">//错误</span></code></pre>
<p>同样，运算符重载是不能改变运算符的优先级</p>
<p><strong>3，</strong> 不能创建新运算符，例如不能定义 <code>operator**()</code> 函数来求幂</p>
<p><strong>4，</strong> 不能重载以下运算符：</p>
<ul>
<li><p>sizeof：sizeof运算符</p>
</li>
<li><p>.  ：  成员运算符</p>
</li>
<li><p>::  ：作用域解析运算符</p>
</li>
<li><p>.*   ： 成员指针运算符</p>
</li>
<li><p>?  :   ：条件运算符</p>
</li>
</ul>
<p><strong>5，</strong> 以下运算符只能通过成员函数进行重载</p>
<ul>
<li><p>=： 赋值运算符</p>
</li>
<li><p>()  ：函数调用运算符</p>
</li>
<li><p>[]  ：下标运算符</p>
</li>
<li><p>-&gt;  ：通过指针访问类成员的运算符</p>
</li>
</ul>
